Here I followed the discussions about shearing ground connection due to rust at the puf.(Self interest!
) A couple of months ago I was looking for contributions to the Lambda because I wanted my changes! In one post I became aware, the one said he had a Lambda with 4 connections! ==References== would be a mass connection. Can the probe be used?? (Unfortunately, I no longer find the post otherwise could ask him himself)Thanks for not hitting and for the answers!
